I’m sorry to hear about the trouble you are having with the NHD-0220D3Z-NSW-BBW-V3.

There is a known issue on our serial LCD modules which affects its operation when used in I2C mode.When using the module’s I2C interface at a clock rate of 100KHz NACKs/bit errors/hanging, may occur.Therefore, if using the I2C interface of these serial LCD modules, a MAX clock rate of 50KHz should be used.

We have updated the I2C section of our datasheet to reflect this information, and the updated specs should be accessible on our website shortly.If you have any questions or need any assistance getting these serial LCD modules working, please contact us by emailing our technical support email nhtech@newhavendisplay.com, or by calling our phone M-F, 8am - 5pm CST (number listed on our website in the contact us section), we're always happy to help!

The Newhaven Display 2.7” Monochrome Graphics OLED module, NHD-2.7-12864UCY3, has reached End-Of-Life and is being replaced by our new and improved 2.7” OLED module, the NHD-2.7-12864WDY3.

The new module has been designed to match the physical dimensions of its predecessor, and will fit into any existing housings/enclosures used currently. However, due to the current OLED panel’s built-in controller being discontinued, the new module will not be a drop-in replacement.

A product EOL (End‐Of‐Life Notification) was sent out on June 8, 2017.

If you are interested in received the Product EOL/Replacement Transition Guide, please see the link below:

The purpose of this document is to highlight and explain the key differences that need to be accounted for when transitioning from the ‘EOL’ to ‘NEW’ 2.7” Monochrome Graphics OLED module from Newhaven Display.

The AR1100 (Resistive Touch Screen Controller IC) shows up like a USB mouse, it works on all operating systems as the computer doesn't even know its a touch screen, it just thinks its a mouse. You can adjust the AR1100 to consider itself a Touch Digitizer, supported by many but possibly not all computers.

You can also re-calibrate the touch screen. We do calibrate it with the 800x480 7" screens but we recommend re-calibrating it if you feel like its not precise enough for your tastes.

If you have a Raspberry Pi available you can re-calibrate the touch IC via USB using the following program:
